Abstract:The hybrid HVAC and HVDC transmission lines in one corridor is a solution to improve the utilization of transmission corridors. However, the hybrid electric field due to the corona of transmission lines must be considered. An experimental model including unipolar DC wire parallel with the single-phase AC wire is established in this paper to measure the ground-level hybrid electric field under different arrangements. The ground-level hybrid electric field is also calculated by the combination method of finite element method (FEM) and finite volume method (FVM). Then, the impacts, such as voltage of the AC wire, the height of AC and DC wires and the adjacent distance between DC and AC wires, are researched. It is helpful for the design of hybrid HVAC and HVDC transmission lines.
